Where is Smart Object option in Layers? - Photoshop Elements 2020

I'd like to try the Liquify feature (can't find that one either), but first need to work with a Smart Object it seems. I can't find it as an option under Layers or anywhere else! Running Photoshop Elements Editor 2020 18.0 on MacOS Big Sur vsn 11.2.

Is it available on this version, and if so, a pointer would be much appreciated!
